Folic Acid, The News Keeps Getting Better

National press has recently taken an interest in the benefits of folic acid, with coverage increasing throughout the media. Folic acid, a B vitamin and other folates helps the body to form red blood cells and aids in the formation of genetic material within every body cell. Folic acid also helps to prevent birth defects. Proponents of dietary supplements have encouraged the use of folic acid by women who are of the child-bearing age for a long time.

The public is becoming increasingly aware of the importance of this nutrient to prenatal development. In a survey done by U.S. Health and Human Services in 2007, about 40% of all women surveyed reported the daily consumption of a supplement that contained folic acid, while about 42% of women surveyed reported that folic acid is the most important vitamin for women of child-bearing age. This study also found that awareness of the benefits differed by age group. Younger women were the least likely to know about the benefits of folic acid, and therefore, were the least likely to consume folic acid. These younger women were also more likely to hear about folic acid from a magazine or newspaper or school or college, rather than their health-care provider.

On the contrary, the women who aged 25-34 and 35-47 were much more likely to hear about folic acid and its benefits from their health-care provider. Because of these results, the U.S. Health and Human Services considers it vital to increase young person education and awareness. Folic acid has long been known to help prevent birth defects. Recent research on folic acid shows that it may also help in preventing premature births, boost baby weights, prevent preeclampsia, reduce risk of Alzheimer’s disease, and even cut male smokers’ stroke risk.

Folate is determined from the term “foliage,” and is a member of the B vitamin family where it can be primarily found in dark leafy green vegetables, legumes, citrus fruits, beets, meat, and wheat germ. Folic acid does not occur in nature and cannot be found in unfortified foods. It is not an active form of the B-vitamin. However, it is the most common form of folate used is supplements and in fortified food products due to the fact that it is highly bioavailable and chemically stable. It is also readily reduced to tetrahydrofolate, which is the active coenzyme form of folate. One study, comparing folic acid from orange juice and folic acid from a supplement showed that the supplement had a better absorption rate than the fortified orange juice.

Although folic acid is not generally associated with side effects, there have been some clinical reports that high level of folic acid can mask a deficiency of vitamin B-12. However, a deficiency of B-12 is very uncommon and it has been determined that only amounts about 3000 – 4000 micrograms per day of folic acid for extended periods of time may have this masking effect, which can in turn be eliminated by supplementing with a few micrograms of B-12.
